Problems solved by technology

Unfortunately, however, installing the solid glass tiles after the solar modules themselves have already been installed adds an extra step to the installation process, thus increasing the overall cost of the system
Also, in known existing integrated solar roof systems, solid glass sheets cannot replace the flexible outer surfaces of the modules (e.g., clear plastic) because doing so would eliminate the Ability of the system to be rolled up for transport and installation

Embodiment Construction

[0024] Referring now to the drawings, FIG. 1 is a top view showing two battens 10A and 10B of an embodiment of the integrated roofing system of the present invention installed on a roof 11 of a building or the like. Although the roof 11 is shown as a "flat roof", it should be understood that the invention may be used with other types of roofs, such as pitched roofs. As shown in Figure 1, and as will be described in detail below, each slat 10 includes a flexible waterproof substrate 12 with a plurality of rigid, glass-covered spaced-apart solar cell arrays 13 (only shown for clarity) some numbered battery packs).

[0025] The substrate 12 is glued or otherwise secured to the surface of the roof 11 (eg, glued decking 14 ) such that the substrate layer lays flat on the surface and the battery pack 13 is exposed to the sun. Since the base plate 12 is made of waterproof material, it will provide the main roofing material for the roof in the area under the battens. The battery pac...

Abstract

An integrated solar cell roofing system includes solar cell array slats. Each plank comprises a length of substrate of flexible waterproof material. A first layer of bonding material is placed on the substrate on which a set of pre-wired photovoltaic cells are disposed. A second layer of bonding material is applied, and a single sheet of rigid glass is disposed on this second layer on each set of PV cells. Heat and vacuum are then applied to melt the bonding material, thereby bonding the PV cells and the glass sheet to the substrate to form spaced apart solar cells thereon. The slats can then be folded into a fan-fold configuration for handling.

Description

[0001] This application claims priority to US Provisional Patent Application 60 / 661,120, filed March 11,2005. technical field [0002] The present invention relates to an integrated solar cell roofing system, and one aspect thereof relates to an integrated solar cell roofing system comprising a flexible roofing material or membrane having a plurality of rigid solar cells integrally formed on its surface battery circuit or solar battery pack, and the invention also relates to a method of manufacturing the system, wherein the rigid solar battery packs are separated from each other and electrically connected to each other so that the roofing material can be folded into a fan-folded package, whereby the rigid The solar arrays are stacked one on top of the other to facilitate shipping and installation of the system. Background technique [0003] Considerable progress has been made in recent years in photovoltaic cells or similar cells for the direct conversion of solar energy int...
